Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual
irina [24]
Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft

Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in

So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall

liberstina [14]

Answer:

The correct option is a

Step-by-step explanation:

From the question we are told that

    The sample size is n =  415

    The sample proportion is  \r p  = 0.49

Now

     The null hypothesis is  H_o  :  p = 0.3

     The alternative hypothesis is H_a  :  p \ne 0.3

The test statistics is mathematically evaluated as

      t  =  \frac{\r p -  p  }{ \frac{\sqrt{ p (1- p )} }{n} }

substituting values

      t  =  \frac{0.49 -  0.3  }{ \sqrt{ \frac{0.3 (1- 0.3 ) }{415} }}

     t  = 8.446
